Abstract
The in-situ measurements for continuously rolling optical films by the chromatic confocal apparatus have been successfully achieved by the authors. The apparatus presented here consists of chromatic confocal to avoid the vibrations caused by the roller machine while working. Without the need of the vertical z axis scan, chromatic confocal can give instant thickness measurements. Therefore, the apparatus possesses the characters of high resolution and fast response. We believe that this system can highly monitor and improve the yield rate in production lines.
